MUSIC-LEAF TURNER.

Application filed March 27, 1815.

To all whom it may concern Be it known that I, ARMANI) A. Tinnrrs, acitizen of the United States, residin at Eouth @maha, in the county ofDouglas and State of Nebraska, have invented certain new and usefulImprovements in Music-Leaf Turners; and I do hereby declare thefollowing to be a full, clean, and exdescription of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to music leaf turners and has for its principalobject to provide a device which is adapted to be folded and carried inthe pocket of the user.

Another object of the invention is to provide a simple and efficientdevice which may be easily and quickly put into operation so that thepages of sheet music may be easily and quickly turned withoutinconvenience to the operator.

A further object of the invention is to provide a novel means forcontrolling the turning of the sheets of music which is carried withineasyreach of the user so that little difficulty will be encountered inthe operation of the device.

lVith these and other objects in view the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawings, in which:

Figure 1 is a perspective view of the music leaf turner in its foldedposition. Fig. 2 is a longitudinal sectional view of the device in itsopen position. Fig. 3 is a top plan view of the device in its openposition showing the cover removed. Fig. 4: is a transverse sectionalview taken on the line H of Fig. 2. Fig. 5 is a detail View of the musicsupport showing the same folded. Fig. 6 is a detail view of one of theclips formed on the ends of the upright, illustrating the bifurcation toreceive a sheet of leaf music and Fig. 7 is a detail view of one of theclips on the end of the arms to receive a corner of a sheet of music.

Referring to the drawing, the numeral 1 designates as an entirety themain body of the device which comprises the bottom 2 having securedthereto'the side walls 3 and 4: and the end walls 5*. The wall 3 formsthe front wall of the device and is formed with suitable apertures 5 forthe reception of the operating shaft which will be more fullyhereinafter described. Hinged t0 the end walls 5 of the device as at 6are the Specification of Letters Patent.

Serial No. 17,447.

covers designated generally by the numeral 7 each of which aresubstantially half of the length of the body 1 and comprises the top 8having the side walls 9 and the end walls 10. The cov r may be securedto the base in a closed position by means of a hook 11 or other suitablefastening means as clearly shown inthe drawing.

Secured within the body 1 near each end are the partition walls 12 whichform a central chamber in which the operating mechanism is mounted.These partition walls are provided with openings 13 which form guidesfor the sliding bars 1% which bars are formed with racks 15 on one sideand the racks 16 on the under side. EX- tending through the apertures 5in the front wall 8 and journaled in suitable bearings carried by therear wall are the horizontal shafts 17 which are provided at their outerends with the thumb pieces 18 l y which they are rotated. Suitable gears19 are mounted on the shafts and are arranged to mesh with the racks 16as clearly shown in Fig. 2. While in the present invention there areshown three bars 1% it is to be understood that any number may be usedwithout departing from the spirit and scope of the invention. Journaledin suitable bearings carried by the bottom wall 2 of the body 1 are thevertically extending shafts 20 carrying the gears 21 which mesh with theracks 15. Formed on the gears but spaced upwardly therefrom are suitabledisks 22 which are provided with apertures 23 for the reception of thelug carried by the innsic support which will be more fully hereinafterdescribed. The shafts 20 are formed with axial bores which cooperatewith the apertures 23 in supporting the music holders in proper place.

The music holders above referred to are designated generally by thenumeral 2t and each consists of the tubular standard 25, 25 and 25*, inwhich the uprights 2G. 26 and 26" are slidable. The uprights arebifurcated at their upper ends and bent over as at 27 to form clips inwhich the edge of the music to be supported is placed. The uprights 26may be adjusted vertically to hold leaf music of different sizes and areheld in their adjusted position within the standards 25 by the setscrews 28. Pivoted as at 29 near the lower ends of each of the standards25 25 and 25 are arms 30, having formed at their free ends suitableclips 31 for the reception of the opposite corners of the music leaves.A suitable arcuate guide 32 is carried by each of the standards 25, 25and 25 and formed with a slot for the reception of a suitable guide pinextending through each arm 30 as clearly shown in the drawings.Depending from the pivoted portion of the standards are suitablecylindrical extensions 33 which are arranged to extend into the axialrecess in the ends of the shaft 20 in which they are held. Lugs 34 arecarried on the arms 30 and these lugs engage in the aperture 23 in thedisks 22 heretofore described. It will thus be seen that the standardsare supported in the shafts and are held against relative rotation bymeans of the disks 22 and lugs 34 respectively, so that any music leafplaced on the supports will be turned upon movement of the respectiverod 14.

In the explanation of the operation of the device, the referencecharacters A, B and C will represent the thumb pieces by means of whichthe shafts A, B and C are controlled. These shafts carry theirrespective gears A B and C which mesh with their respective rack bars AB and C Meshing with the racks 15 of the respective rack bars are thegears a, b and cwhich are mounted on the shaft. It will thus be seenthat when the thumb piece A is rotated the shaft A will also rotatethereby causing the gear A to move the bar A This will cause the gear ato rotate and thereby turn the shaft d in its bearing and thus cause thesheet of music carried by the standard 25 mounted on said shaft to beturned, so that the opposite side thereof will be exposed. When it isdesired to turn the second sheet of music the thumb piece B is turnedand this will cause the shaft B to rotate thereby moving the gear B sothat the rack bar B will slide through its bearings and cause the rack15 to engage the gear I) and turn the same, thus rotating the shaft 6carrying the standard 25 whereby the second sheet of music is turned.The same operation is gone through in turning the third sheet of musicby the manipulation of the thumb piece C and it will thus be seen that adevice is provided which will easily and quickly turn the pages withoutinconveniencing the user.

WVhile in the foregoing there has been shown and described the preferredembodiment of this invention it is to be understood that such changesmay be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the appended claims.
